ABSTRACT

A rewinding machine for the production of rolls of wound-up weblike material is described, comprising; a winding-up system ( 7, 9, 11 ); a system ( 27 ) for severing the weblike material (N) which, on completion of the winding-up of each roll (R), severs the weblike material, forming a free final edge and a free initial edge; an adhesive applicator ( 121 ) for applying the adhesive intended to seal the free final edge of the weblike material of each roll before the roll is unloaded from the winding-up system.

TECHNICAL FIELD

[0001] The present invention relates to a rewinding machine for theproduction of rolls of wound-up weblike material, for example rollsintended for the production of small rolls of toilet paper, kitchentowel and the like.

[0002] In particular, but not exclusively, the invention relates to arewinder of the peripheral or superficial type, that is to say one inwhich the roll or log being formed is retained in rotation in awinding-up cradle by means of winding-up members which are in contactwith the roll being formed over its peripheral surface, transmittingthereto the rotational winding-up movement.

[0003] The invention also relates to a winding method which can beimplemented on the abovementioned rewinder.

STATE OF THE ART

[0004] In the paper converting industry, use is frequently made ofmachines known as winders or rewinders, which receive an incomingweblike material coming from a parent reel or plurality of parent reels,to wind it up in the form of rolls or logs of diameter equal to thediameter of the finished product and great length. These rolls or logsare subsequently cut orthogonally to their axis to form small rolls oftoilet paper, kitchen towel and the like.

[0005] Machines of this type, based on the peripheral winding-upprocedure, are described and illustrated, for example, in: U.S. Pat. No.4,723,724, U.S. Pat. No. 4,856,725, U.S. Pat. No. 4,828,195, U.S. Pat.No. 4,962,897, U.S. Pat. No. 4,487,377, U.S. Pat. No. 4,931,130, U.S.Pat. No. 5,248,106, U.S. Pat. No. 5,368,252, GB-A-2 105 688, WO-A-94/21545. Machines based on the central or mandrel winding-up procedure aredescribed in U.S. Pat. No. Re-28,353, U.S. Pat. No. 3,532,572, U.S. Pat.No. 3,552,670, U.S. Pat. No. 3,567,552, U.S. Pat. No. 3,734,423.

[0006] The rewinding machines are normally designed on a large scale andoperate at very high speeds. In particular, the present trend is towardproducing rewinding machines suitable for processing weblike material ofever-increasing width.

[0007] In some applications, however, it would be appropriate to haverewinding machines of modest size available, in particular to meet theneeds of emerging markets where high production speeds are notnecessary.

[0008] To meet these needs, a peripheral rewinding machine ofparticularly modest size has been developed and is described inWO-A-97/32 804. This rewinding machine provides a special winding-upsystem, with means of gluing the final free edge of the roll locateddownstream of the winding-up cradle. Normally, the unloading of thefinished log and its gluing require a cyclical slowing of the productionline in order to obtain correct positioning of the free edge of theweblike material to be glued in order to seal the roll.

OBJECTS AND BRIEF DESCRIPTION OF THE INVENTION

[0009] It is an object of the present invention to provide a machine,especially but not exclusively of the peripheral or superficial type, ofmodest size, and therefore particularly easy to transport and such as totake up little space when in use.

[0010] According to a particular aspect, it is also an object of theinvention to produce a compact machine in which the feed speed of theweblike material need not be reduced at the end of each winding-upcycle.

[0011] Substantially, these and other objects and advantages, which willbe clear to the person skilled in the art from reading the text thatfollows, are achieved in a rewinding machine equipped with a winding-upsystem, generally of the central or peripheral type, and with a systemfor severing the weblike material at the end of each winding-up cycle inorder to generate a final edge and an initial edge, wherein an adhesiveapplicator applies the adhesive to the final free edge of each roll in aposition upstream of the roll in the final phase of winding-up in thewinding-up system.

[0012] Normally, contrary to what is envisaged by the present invention,the adhesive for sealing the free edge is applied to the final edge orto the roll downstream of the winding-up system, when the roll has beenunloaded from said system. For this purpose, suitable gluing machinesare usually provided, disposed in line with the rewinding machine,optionally with the interposition of a storage unit. This makes the linecomplex and bulky.

[0013] According to the invention, conversely, the adhesive is appliedto an end portion of the weblike material before the latter is wound uponto the roll and before the roll is unloaded from the winding-upsystem. This makes the machine more compact and enables other advantagesto be achieved, which will become clear in due course.

[0014] U.S. Pat. No. 4,487,377 describes a system in which the adhesiveis applied to the final edge of the weblike material before completionof the roll. However, in this case, the adhesive is not applied by anapplicator directly onto the weblike material. To the contrary, it isdelivered onto a winding-up core and the latter, when it is insertedinto the winding-up system, transfers some of the adhesive appliedthereto to the final edge in order to achieve sealing thereof. Thisknown solution has significant limitations.

[0015] Specifically, it is applicable only with special winding-upsystems and only with certain systems for severing the weblike materialand introducing new winding-up cores. Furthermore, it is not applicablein cases where the winding-up takes place without a central core. Itshould also be borne in mind that it is not always possible orappropriate to use the same adhesive for the final free edge of a rolland to anchor the initial free edge to the winding-up core in order toinitiate the winding-up of the subsequent roll.

[0016] These limitations are overcome by the present invention.

[0017] According to a particularly advantageous embodiment of theinvention, the adhesive is applied to the weblike material before thelatter is cut, torn or otherwise severed by the severing system. Thismay take place, for example, by disposing the adhesive applicatorupstream of the severing system. However, in principle, it would also beconceivable to dispose the adhesive applicator downstream of the area inwhich the severing system acts or on the severing system itself.

[0018] Although the winding-up system may be of any kind, including thecentral type (i.e. the type in which the winding-up movement is impartedto the roll by means of a central mandrel around which the material iswound up), according to a particularly advantageous embodiment of theinvention the winding-up system comprises a peripheral winding-upcradle. In this case, the adhesive applicator may be disposed upstreamof the winding-up cradle, for example facing one of the winding-up rollswhich form part of said cradle.

[0019] By comparison also with the more compact rewinding machinesdescribe, in WO-A-97/32 804, the present invention provides thepossibility of a further reduction in the bulk of the machine and thepossibility of achieving a high level of reliability and precision ingluing, even without temporary reductions of the feed speed of theweblike material.

[0020] Furthermore, it is possible to wind up even rolls of largediameter. This is possible because, once the adhesive has been applied,before completion of the winding-up of the final free edge of the roll,the latter performs a rotation in the winding-up cradle and subsequentlyon an unloading surface to exert pressure on the final free edge andstabilize the latter for gluing to the final turn of the roll. Inpractice, the roll may also perform a complete revolution in thewinding-up cradle before being unloaded, so that at the time ofunloading the final free edge has already been pressed against the lastturn of the roll.

[0021] In the traditional systems, conversely, this operation requiresespecially in the case of rolls of large diameter—very long rollingsurfaces in order to ensure that pressure is always exerted on the finalfree edge, and hence large bulk.

[0022] In practice, the adhesive applicator may comprise one or morenozzles disposed side by side to spray the necessary dose of adhesiveonto the weblike material. However, different systems for applying theadhesive, for example a contact system with brush or pad members whichtouch the weblike material, transferring the necessary adhesive thereto,are not ruled out, although the use of nozzles is advantageous becauseit is simpler in design and from the standpoint of maintenance andpreparation, as well as being more flexible.

[0023] In a practical embodiment, the winding-up cradle may possess awinding-up system comprising a first winding-up roller and, optionally,a second and a third winding-up roll, in accordance with a technologyknown per se, although the possibility of a different configuration ofthe winding-up cradle is not excluded.

[0024] When at least a first winding-up roller is provided, the spraynozzle or nozzles which apply the adhesive in order to seal the freeedge of the weblike material are disposed, relative to the firstwinding-up roll, in a manner such as to spray the adhesive onto theweblike material when the latter is supported and moved around saidwinding-up roll. The means for severing the weblike material areadvantageously disposed downstream, in the direction of movement of theweblike material, relative to the position of the spray nozzles whichapply the adhesive.

[0025] The rewinding machine may be of the type which winds up ontotubular cores, but the possibility is not excluded of applying the samecriterion to rewinding machines which produce rolls of weblike materialwound-up without a central winding-up core, using known winding-uptechniques described, for example, in EP-A-0 580 561 and EP-A-0 611 723.

[0026] According to a further aspect of the present invention, aparticular configuration of an embossing and laminating unit is alsoproposed, of particular compactness, capable of being inserted into arewinding machine of modest size. According to this aspect of theinvention, the embossing unit has a first and a second embossingcylinder and a first and a second pressure roller, the embossingcylinders and the pressure rollers being supported by the side frameswhich also support the perforating unit, the winding-up cradle of therewinding machine, particular compactness thereby being achieved.

[0027] In practice, a reduction in bulk may advantageously be obtainedby placing the embossing cylinders one above the other vertically, in amanner such that the first embossing cylinder is located above thesecond embossing cylinder, for example and advantageously (but notnecessarily) with the axes placed one above the other in a verticalplane. In this case, the first pressure roller is positioned above thefirst embossing cylinder, while the second pressure roller is disposedbelow the second embossing cylinder, but offset laterally relative tothe plane containing the axes of the embossing cylinders, which planemay advantageously and preferably (but not necessarily) be approximatelyvertical. In this configuration, the winding-up cradle is situated,relative to the plane in which the axes of rotation of the embossingcylinders lie, on the side opposite that on which the second pressureroller is located. In this manner, as will become clear from thedetailed description of an example of embodiment, a configuration ofparticularly reduced size is achieved.

[0028] A system for combining the plies that constitute the weblikematerial may be associated with the embossing unit. For example, aply-bonding unit may be provided. in an alternative embodiment, anadhesive dispenser may be provided which, in a manner known per se,applies an adhesive to one of the two plies of the weblike material,after the ply has been embossed. In this case, the adhesive dispenser isadvantageously disposed above the second pressure roller, again in orderto obtain a very compact configuration. The possibility of disposingboth an adhesive dispenser and a ply-bonding unit in the same machine,so as to permit the user to employ both methods, is not excluded.

[0029] The invention also relates to a winding-up method for theproduction of rolls of weblike material.

[0030] Further advantageous features of the machine and method accordingto the invention are indicated in the attached claims.

BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The invention will be better understood by reference to thedescription and the attached drawing, which shows a practical,nonlimiting example of said invention. In the drawing:

[0032]FIG. 1 shows a lateral view of the rewinder according to theinvention; and

[0033] FIGS. 2 to 4 show successive phases of the winding-up cycle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION

[0034] A detailed description will be given below of a particularlyadvantageous embodiment of the invention, complete with accessories andelements which may also, in part, be omitted. The embodiment illustratedis of the type having tubular winding-up cores on which the individualrolls are formed, but, as stated previously, the machine may also bedesigned for winding-up without a tubular core.

[0035] The rewinder, generally designated 1, comprises side frames 3 onwhich is mounted a winding-up cradle, generally designated 5, andcomprising in the example shown a trio of winding-up rollers 7, 9 and11. The first winding-up roller 7 forms, together with the secondwinding-up roller 9, a gap 13 through which the weblike material and theroll pass at the start of the phase of formation around the respectivewinding-up core A.

[0036] The first winding-up roller 7 receives the weblike material Nfrom an unwinder (not shown). The third winding-up roller 11 is mountedon an arm 15 oscillating about an axis 17 in order to adapt to theincrease in size of the roll being formed. Downstream of the winding-upcradle is disposed an unloading chute 21 with a roll-stopping device 23controlled by an actuator 25, which intervenes to stop the movement ofthe rolls and unload, in a controlled manner, the individual rollsdelivered to the winding-up cradle along the chute 21.

[0037] Below the first winding-up roller 7 extends a curved rollingsurface 25 along which the winding-up cores A roll in the first phase ofwinding-up of the weblike material N, in accordance with a technologyknown and described in detail in WO-A-94/21 545, to which reference ismade for more descriptive details. Reference 27 designates an elementfor severing the weblike material, which rotates in a controlled mannerabout an axis of rotation 29 and interacts with the first winding-uproller 7 to perform the severing of the weblike material at the end ofthe winding-up of each roll, so as to generate a final free edge, whichis eventually wound onto the roll just completed, and an initial freeedge which is caused to adhere to the next winding-up core.

[0038] The winding-up cores A are fed to the winding-up cradle 5 bymeans of a feeder 31 which comprises a re-emergence guide for the coresA, designated 33. The tubular cores A are inserted into the re-emergenceguide 33 from below, sliding or rolling along a base surface 35 of ahopper 37 in which is also located an agitator 39 that prevents thecores from becoming jammed. The cores are unloaded individually onto theunloading surface 47 and retained in the waiting position by an elasticblade 49.

[0039] A rotating inserter 51, synchronized with the rotation of thesevering means 27, acts to push each tubular core A into the channeldefined by the rolling surface 25 and the first winding-up roller 7, atthe start of each winding-up operation.

[0040] Above the surface 47, in alignment with the holding position ofthe cores A before insertion into the channel between the rollingsurface 25 and the first winding-up roller 7, are disposed a pluralityof first nozzles 53 which apply to the temporarily wafting tubular coreA the adhesive necessary for the adhesion of the initial free edge ofthe weblike material. As an alternative to the gluing system, othersystems may be used, for example suction or electrostatic systems orothers known in the art.

[0041] Along the path of the weblike material N coming from the unwinder(not shown) is disposed an embossing and laminating unit generallydesignated 61 and comprising a first embossing cylinder 63 rotatingabout an axis of rotation 63A and a second embossing cylinder 65rotating about an axis of rotation 65A. The two embossing cylinders,made for example from steel or another hard material, have surface tipsor protuberances which perform the embossing of the material.

[0042] Interacting with the first embossing cylinder 63, which is in aposition approximately vertically above the second embossing cylinder65, is a first pressure roller 67 supported by an arm 69 hinged at 71and pressed against the embossing cylinder 63 by means of an actuator73. Interacting with the second embossing cylinder 65 is a secondpressure roller 75 supported by an arm 77 hinged at 79 and pressedagainst the embossing cylinder 65 by means of an actuator 81. As can beseen in FIG. 1, the three axes of rotation, of the embossing cylindersand of the pressure roller 67, are approximately vertically one abovethe other, in other words they lie in a common vertical plane shown bythe line P-P. Conversely, the axis of rotation of the pressure roller 75is offset and is located, relative to the plane in which the axes ofrotation 63A, 65A of the embossing cylinders 63, 65 lie, on the oppositeside from the winding-up cradle. A particularly compact configuration isthus obtained.

[0043] The first and second embossing cylinders 63, 65 and therespective pressure rollers 67 and 75 are supported by the same sideframes 3 that support the members forming the winding-up cradle.

[0044] Interacting with the first embossing cylinder 63 is an adhesivedispenser 83, comprising in this example a distributor 85, a firstscreened cylinder 87 and a second plate cylinder 89, in contact with theply of material passed around the first embossing cylinder 63 in orderto apply, in a manner known per se, an adhesive to the embossedprotuberances of the ply generated on the surface of the embossingcylinder 63. The adhesive dispenser is located above the pressure roller75.

[0045] Also interacting with the first embossing cylinder 63 is acoupling or laminating roller 91 supported by an arm 93 hinged at 95 andstressed against the embossing cylinder 63 by means of apiston-and-cylinder actuator 97. By means of this, the two plies,separately embossed on the two embossing cylinders 63, 65, are coupledby lamination after the application of the adhesive.

[0046] Two plies of weblike material, designated V1 and V2, are fed tothe embossing and laminating unit 61 and are embossed separately, thefirst between the embossing cylinder 63 and the pressure roller 67 andthe second between the embossing cylinder 65 and the pressure roller 75.The ply V2 is then detached from the second embossing cylinder 65 andplaced gently on the first ply V1 passed around the first embossingcylinder 63. The two plies, thus placed one above the other, arelaminated between the first embossing cylinder 63 and the laminatingroller 91 to form the weblike material N. An application of adhesivebeing provided by the dispenser 83, the lamination results in the twoplies V1 and V2 being bonded one to the other.

[0047] In the example of embodiment shown, there is provided along thepath of the weblike material N coming from the laminating/embossing unit61 a ply-bonding unit 101 comprising a cylinder 103 with which interactply-bonding rollers 105 stressed under pressure against the cylinder 103by means of one or more expansion boxes 107 which are expanded to highpressure. The ply bonding unit 101 may be used in addition to theembossing unit 61, for example when the latter is operating withoutadhesive, because it lacks the dispenser 83 or because the latter hasbeen taken out of service. This does not exclude the possibility thatthe machine lacks the embossing unit 61 and is equipped only with theply-bonding unit 101 which provides the coupling of the two plies V1,V2, appropriately transported to the ply-bonding unit 101, for exampleby being passed around the roller 91. It is also possible to arrangethat the ply-bonding unit 101 is entirely absent and that the machine issupplied solely with the embossing and laminating unit 61, with theassociated adhesive dispenser 83. In this case. the path of the weblikematerial N will be slightly modified.

[0048] Along the path of the weblike material N, between the ply-bondingunit 101 and the winding-up cradle 5, a perforating unit 111 isprovided, comprising a rotating blade-supporting roller 113 and a fixedroller 115 bearing a counter-blade. The perforating unit 111 may be ofthe traditional type and is not described in detail.

[0049] The weblike material N which passes through the perforating unit111 is provided with a series of perforation lines orthogonal to thelongitudinal course of the weblike material N, which perforation linessubdivide the weblike material N into a series of slips or sheets forsubsequent use by the end consumer.

[0050] The perforated weblike material N coming from the perforatingunit 111 is passed around a cylinder 117 and, from there, around thefirst winding-up roller 7 in order to be passed to the winding-upcradle.

[0051] Interacting with the first winding-up roller 7 is a series ofspray nozzles 121 which serve to apply an adhesive to the weblikematerial N in order to perform the sealing of the final free edge of theweblike material at the end of the winding-up of each individual roll,following the severing of the weblike material by the severing member27.

[0052] As clearly illustrated in FIG. 1, the nozzles 121 (which areprovided in appropriate numbers and suitably spaced to ensure correctgluing also of areas over the length of the roll, in other words overthe width of the weblike material) are disposed in a manner such as tospray the adhesive onto the weblike material at the desired moment,before said weblike material passes into the channel defined by thewinding-up roller 7 and the rolling surface 25, and thus before themember 27 for severing the weblike material acts upon it. In this way,the adhesive, subsequently intended to seal the roll, is applied to theweblike material before the latter is severed.

[0053] Expediently, the nozzles 121 may be mutually spaced relative toone another in a manner such that the adhesive distributed thereby doesnot affect those areas of the weblike material N with which the severingmember 2 ⁻ is in contact, in a manner such that the latter does notbecome contaminated with adhesive during each winding-up cycle.

[0054] More expediently, moreover, contamination of the severing member27 by the adhesive sprayed by the nozzles 121 can be prevented withappropriate timing of the actions of the two members. Specifically, asis known from the prior art, the severing member 27 may be phased,relative to the perforation lines produced by the perforating unit 115on the weblike material N, in a manner such that the weblike material issevered by tearing at a position between the roll being wound up betweenthe rollers 7, 9 and 11 and the point of contact between the severingmember 27 and said weblike material, in other words the point at whichthe weblike material is pinched between the severing member 27 and thefirst winding-up roller 7. Since the adhesive applied by the nozzles 121is to remain on the end part or tail of the weblike material which isbeing wound up on the roll being completed, the spray nozzles 121, theperforator 111 and the severing member 27 may be mutually phased in amanner such that the severing action performed by the severing member 27on the weblike material takes place when the perforation along which theweblike material parts as a result of the pinching action of thesevering member 27 is located at a sufficient distance from the area ofaction of said member 27, so that the adhesive previously sprayed by thenozzles 121 onto the weblike material is reliably outside the area ofcontact between the weblike material and the severing member 27.

[0055] While the foregoing has provided a description of the possibilityof using a series of spray nozzles 53 to apply an adhesive to thetubular cores A before the latter are inserted between the rollingsurface 25 and the winding-up roller 7, this does not exclude thepossibility that the adhesive necessary for anchoring the initial freeedge of the weblike material to the winding-up core A is applied by saidnozzles 121. To this end, provision may be made for the latter to beactuated twice, once in order to apply the adhesive to the area ofweblike material N which, after the severing performed by the severingmember 27, will form the tail or final end of the roll, and a secondtime to the weblike material which will enter into contact with thetubular winding-up core A. In this case also, provision being made forinterrupting the delivery of the adhesive by the spraying nozzles 121,it will be possible to prevent contamination of the severing member 27by the adhesive. In practice, the severing member will act between twolinear areas of adhesive, the more forward one in order to seal thefinished roll and the more rearward one in order to initiate thesubsequent winding-up.

[0056] The use of two series of nozzles 53 and 121 is expedient when theadhesives used for sealing the final edge of the roll and anchoring theinitial edge to the core are of different nature and features. Thisdepends on the type of product wound up and/or the winding-up speed.

[0057]FIGS. 2, 3 and 4 show three consecutive phases in the operation ofwinding-up a roll of weblike material.

[0058] In FIG. 2, the roll R is in an intermediate phase of formation. Anew core A, in this example, has already been positioned for subsequentinsertion. FIG. 3 shows the phase of completion of the winding-up of theroll, with the separating member which rotates in the direction of thearrow f27 and enters the channel defined between the rolling surface andthe upper winding-up roller 7. The nozzles 121 spray the adhesivenecessary for the sealing of the final edge. FIG. 3 also shows the phaseof delivery of the adhesive to the new core A by the nozzles 53 on theweblike material N before its severing. This delivery may besimultaneous or staggered in time, and in particular advanced, bycomparison with the delivery by the nozzles 121. FIG. 4 shows thesubsequent phase, in which a new core A has already been inserted intothe channel defined between the rolling surface 25 and the winding-uproller 7, in contact with said rolling surface and with the weblikematerial N passed around the winding-up roller 7. Downstream of thesevering member, the weblike material N has been torn to form a finaledge LF which eventually becomes wound up onto the roll R, and to whichthe adhesive C has been applied by the spray nozzles 121. LI designatesthe initial edge which is wound up onto the new core. The unloading ofthe roll R from the winding-up cradle takes place in a manner known perse.

[0059] In the example shown, the machine also has a printing unit,generally designated 131 and comprising an inker 133, a screenedcylinder 135 and a plate cylinder 137 which bears the plate on which isengraved the design, decoration, text or other information to be printedon the weblike material. In this example, only the ply V1 of the weblikematerial N is caused to pass onto the return cylinder 139 with which theplate cylinder 137 interacts, while the other ply V2 is passed, withoutprinting, to the embossing unit or, possibly, directly to theply-bonding unit.

[0060] It is understood that the drawing shows only a simplification ofthe invention, provided by way of a practical demonstration, and that itmay be varied in shapes and arrangements without thereby departing fromthe scope of the concept underlying said invention.
